ZP-900 Hydraulic Anti-Foam 12 oz

HOW IT WORKS: ZP-900 HYDRAULIC contains a wet anti-wear lubricant and dry dielectric lubricant, pour point depressant, viscosity index improver, foam reducer, oxidation inhibitor and seal revitalizer. This formulation will not reduce fluid lubricating ability as silicone defoamants often do. It reduces the most frequent problems with hydraulic systems: wear, heat, oxidation, cavitation and leaks. Pump, cylinder and valve wear are virtually eliminated by the surface and subsurface lubrication. By forming a barrier between metal to metal contact, it reduces friction, increasing the load carrying capacity of the system and reducing pump strain. This also reduces friction heat buildup, resulting in less oxidation, varnish, sludge and acids. Valves are freed, and the hydraulic oil lasts longer. WHAT TO EXPECT: Foaming develops as pumps pull in air and mix it with oil. Air may enter due to faulty seals, low fluid level, or even during normal operation. Excess noise in the pump indicates cavitation, which is the formation and collapse of vapor bubbles in the oil. When bubbles collapse, the effect is that of miniature hammer blows, which work to destroy the pump. ZP-900 guards against disastrous pump cavitation with a defoamant and against the power losses that occur when bubbles are in the hydraulic system. ZP-900 reduces the heat load and adds a viscosity index improver to keep oil from thinning out. At 120°F or below, oil oxidizes very slowly. Above 135°F, the rate of oxidation doubles for each 18° increase in temperature. Oxidation leads to sludging, causes formation of harmful acids and creates more heat. Seals deteriorate, and thin, hot fluid leaks out. Hoses fail from being exposed to excess heat, resulting in more fluid loss and downtime. ZP-900 will keep seals pliable, reduce heat and with our defoamant and viscosity improver, keep pumps from cavitating. APPLICATIONS: ZP-900 is compatible with all standard hydraulic systems. 12 oz bottle.
